Portfolio overview

Epoch Company, Ltd. has been granted 131 US utility patents between 2015 and 2025, placing Epoch Company, Ltd. at rank #2,912 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.0 claims per patent with primary concentration in A63H (TOYS, e.g. TOPS, DOLLS, HOOPS OR BUILDING BLOCKS). As a Foreign Corporation, Epoch Company, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Epoch sits between Ashley Furniture Industries, Llc (131 patents, rank #2,908) and Shenzhen Qianhai Patuoxun Network AND Technology Co., Ltd. (131 patents, rank #2,916) - the closest US assignees by grant volume. The composite Innovation Score of 34.4/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 92 grants, compared with 39 in the 2015–2019 window, a +136% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Epoch Company, Ltd.'s 2.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Epoch Company, Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
